The tobacco mouthpiece 1 and the tobacco rod 2 are in rotatable connection through the connecting part 5. The tobacco mouthpiece 1 and the tobacco rod 2 of the embodiment can be opened and closed through the connecting part 5 and the sliding part 4. When in use, the sliding part 4 and the connecting part 5 are used to slide and rotate the tobacco mouthpiece 1 to open the cut tobacco heating device. At this time, the material feeding and discharging opening 31 of the heating cup 3 is exposed, the cut tobacco is put into the heating cup 3, then the tobacco mouthpiece 1 is returned to its original position, and the cut tobacco heating device is closed for smoking. When smoking is completed, through the sliding part 4 and the connecting part 5, the tobacco mouthpiece 1 is slid and rotated to open the cut tobacco heating device and the cut tobacco and the residue after smoking is poured out, and then the cut tobacco heating device is closed. On the one hand, it is easy to load and unload the cut tobacco. On the other hand, instead of using cigarettes, cut tobacco is loaded into the heating cup, and while smoking, the smoke produced by the heated cut tobacco can be inhaled directly without the paper paste of cigarettes, which makes the taste and the experience better.

As shown in FIG. 3, the connecting part 5 of the embodiment includes a connecting member 51 and a rotating shaft 52, and the connecting member 51 is provided on the rotating shaft 52. The sliding part 4 is preferably a sliding groove, one end of the connecting member 51 is connected to the tobacco mouthpiece 1 or tobacco rod 2, and another end is slidably disposed in the sliding groove. Specifically, the connecting member 51 is slidably disposed in the sliding groove through the rotating shaft 52, and can be rotated relative to the sliding groove to open or close the cut tobacco heating device, which is simple in structure and easy for operation. In other embodiments, the sliding part 4 may also be a slide rail, a bar-shaped hole, an arc-shaped hole, a waist-shaped hole, etc.

Furthermore, the cut tobacco heating device further includes an upper housing 6, the upper housing 6 is provided with a tobacco cavity 61, and the tobacco mouthpiece 1 is detachably provided on the upper housing 6 and communicated with the tobacco cavity 61. Specifically, in this embodiment, taking the sliding groove on the tobacco rod 2 as an example, one end of the connecting member 51 is connected to the upper housing 6, and another end is slidably disposed in the sliding groove through the rotating shaft 52. When in use, slide the upper housing 5 first, then turn the upper housing 6 to drive the tobacco mouthpiece 1 to move at the same time, thereby opening the cut tobacco heating device. The sliding groove of the embodiment can also be provided on the upper housing 6, and the connecting member 51 is disposed on the tobacco rod 2.

As shown in FIG. 4, the tobacco mouthpiece 1 is provided with a clamping slot 11, and the tobacco mouthpiece 1 is detachably disposed in the upper housing 6 through the clamping slot 11. This makes it easy to replace the tobacco mouthpiece 1 and improve the utilization rate of the cut tobacco heating device. The tobacco mouthpiece 1 of the embodiment can also be detachably provided on the upper housing 6 by means of a snap structure or the like.

In the embodiment, the shape of both the upper housing 6 and the tobacco rod 2 are cylindrical, two sliding grooves are provided, and two connecting parts 5 are also provided. The two connecting parts 5 are symmetrically disposed on the upper housing 6, and the position of the sliding grooves corresponds to the position of the connecting parts 5.

As shown in FIG. 5, the cut tobacco heating device further includes at least one first limiting member 7 for limiting the position of the rotating shaft 52, and the first limiting member 7 is provided on the inner wall of the sliding groove and is located at the upper end of the sliding groove. In this way, when the upper housing 6 is slid and then rotated, the first limiting member 7 can prevent the upper housing 6 from sliding downward, avoiding the cut tobacco heating device from being closed and facilitating the loading and unloading of the cut tobacco.

In the embodiment, the shape of the first limiting member 7 is semi-circular, two first limiting members 7 are provided, and the two first limiting members 7 are symmetrically disposed on both sides of the sliding groove, which can strengthen the limiting effect of the rotating shaft 52 and avoid the connecting member 5 from sliding downward. At the same time, the first limiting member 7 is semi-circular, so that the rotating shaft 52 can be easily moved to the upper end of the first limiting member 7, which is convenient for operation.

Furthermore, the cut tobacco heating device further includes at least one second limiting member 8 for limiting the position of the rotating shaft, and the second limiting member 8 is provided on the inner wall of the sliding groove and is located at the lower end of the sliding groove. The second limiting member 8 can restrict the rotating shaft 52 from sliding upward when the cut tobacco heating device is closed, avoiding the cut tobacco heating device from being opened when it is not in use.

In the embodiment, the shape of the second limiting member 8 is semi-circular, two second limiting members 8 are provided, and the two second limiting members 8 are symmetrically disposed on both sides of the sliding groove, which can strengthen the limiting effect of the rotating shaft 52 and avoid the connecting member 5 from sliding upward. At the same time, the second limiting member 8 is semi-circular, so that the rotating shaft 52 can be easily moved to the lower end of the second limiting member 8, which is convenient for operation. Further, the shape and size of the second limiting member 8 is the same as the shape and size of the first limiting member 7, which is convenient for processing.

As shown in FIG. 4, the cut tobacco heating device further includes a power supply assembly 9 disposed in the tobacco rod 2, which is electrically connected to the heating cup 3 and can control the heating of the heating cup 3 to heat the cut tobacco inside the heating cup 3.

Furthermore, the cut tobacco heating device further includes a tobacco pipe 62, which is disposed in the tobacco cavity 61, one end of the tobacco pipe 62 is communicated with the tobacco mouthpiece 1, and another end is communicated with the material feeding and discharging opening 31 of the heating cup 3. When in use, the smoke produced by the heated cut tobacco reaches the tobacco mouthpiece 1 through the tobacco pipe 62 and is inhaled by the user, and the upper housing 6 can isolate the heat generated by the heated cut tobacco to avoid scalding the user.

As shown in FIG. 2, the cut tobacco heating device further includes a blocking screen 63 for blocking the cut tobacco or tobacco ash, and the blocking screen 63 is mounted on the tobacco pipe 62 and located at an end thereof which is away from the tobacco mouthpiece 1. Specifically, the blocking screen 63 is mounted at the bottom end of the tobacco pipe 62 to prevent cut tobacco or tobacco ash from entering the tobacco pipe 62. Of course, the blocking screen 63 can also be disposed inside the tobacco pipe 62.

The operation process of the embodiment is as follows:

-   Pull the upper housing 6 to the top end of the sliding groove, turn     the upper housing 6, and the material feeding and discharging     opening 31 of the heating cup 3 is exposed. Put the cut tobacco into     the heating cup 3, return the upper housing 6 to its original     position, and control the heating cup 3 to heat the cut tobacco     through the power supply assembly 9. When smoking is complete, pull     and turn the upper housing 6 to pour out the tobacco ash.
